Than some project with a relationship to vBulletin like CentOS has to RHEL should be possible, yet I have never heard of one ^_^.

Maybe Stallman should have tried LibreWare before he tried Free Software?

Open Source is actually in the dictionary:

Code:

open source
— n
a. intellectual property, esp computer source code, that is made freely available to the general public by its creators
b. Compare closed source ( as modifier ): open source software
closed source

Which to my knowledge would make vBulletin nether Open nor Closed source, due to it's distribution and licensing terms. I've usually used the words "Proprietary software" for a reason, hehe.
